. *rt will'be understood that thefiremans hose :hose, forthe purpose of thawing it out.

is laid from'the watersupply tothefire ina con- .tinuouslinetliat includes many sections of hose that are coupled together with metal couplings. Afte'r the fireI has' been put out to uncouple these sections and roll each section up separately for the purpose of taking it back to quarters. In the winter time the metal couplings freeze up so that it. is impossible in very cold weather to uncouple the sections.

My invention has for its object to provide a device that can be applied directly to a hose coupling, more especially the coupling of a firemans An object of my invention is to provide a device or box that is made of two sections hinged and put in'place coupling.

Another object of the device is to make it in such manner that asmall amount of gasoline can be placed therein and burnt therein, causing the generation of heat pling and thaw it out.

Another object of the invention is to provide a device that can be closed around the coupling enough to heat the couand yet have sufficient air draft, therein to permit pose of heating the coupling.

hose coupling.

In the lower section is placed a semicircular channel or trough l, concentric with the opening I 6, in whichthe ring. 5 on the female part of the coupling is adapted to rest. In the upper section 2 a corresponding channel or hood 6 is provided,which is adapted to embrace. or cover over the ring 5 referred to. When the upper section is closed on the lower section, as shown in Figure 4, these two channels form a mutilated circular trough that nearly surrounds the ring 5. The ends of the trough sections do not quite abut, but an open space is left at each side thereof to provide clearance for ventilation or accumulation of ice, etc. The channel 4 is attached to one side of the section I by three screws 7, 8 and 9 which extend through the side and engage the trough. The trough is spaced away from the side by means of collars l interposed around the screws andbetween the trough and the side. Similar screws ll, l2 and i3 are used to hold the upper channel in place and support it from the side of the upper section 2. The channel 6 has an opening l4 at the top thereof which registers with a similar opening l5 inthe top of the section 2, through which air or the products of combustion can pass. Additional air holes l1, l8 and I 9 are provided in the top section for ventilation.

In the lower channel 4 is provided bridges and 2| on which the lugs provided on the ring 5 of the hose coupling are adapted to rest and by which the coupling is held accurately in place.

, A shoulder 22 is provided on the lower section of the side opposite the hinge on which the lower edge of the upper section is adapted to engage or rest.

A handlef25 is provided, pivoted on the upper section and adapted to engage with the lower section, by which the box may be carried.

In practice this device is opened and placed on the ground at the side of the coupling to be heated. A spoonful of gasoline is placed in the lower trough 4. This gasoline is then set on fire and the coupling and the hose is lifted and the coupling is dropped into place in the lower section. The upper section is then closed on the lower section and left there. By the time the gasoline has burnt itself out, or shortly thereafter, the coupling has been heated enough to Two of the upright parallel circular-*opening which; when the 'sectionsare brought. together, i that. alreeadaptedl to receive or close'around the a I claim:
